As compact and flexible as QA can get
The Cobia Flex R/F offers you the convenience to make your X-ray Quality Control as quick and accurate as possible. It is just as easy as the Cobia Smart but with even more possibilities. It has an internal detector, a detector input that offers the ability to connect different probes and ion chambers, and an optional built-in mAs. The measured values can be read directly from the large and clear display, and stored in the Cobia Flex R/F to read later.
It allows you to determine patient safety every day!
Cobia Flex R/F users also have the possibility to use a tablet or a PC, saving data to a computer, printing reports, using analyses, and much more. The X-ray QA software, Ocean, exhibits the Cobia’s capabilities and adds benefits that make the workflow more practical and simple. Ocean makes it possible to perform remote X-ray QA measurements with your Cobia Flex R/F. You simply connect to your Cobia Flex R/F, via Bluetooth, or with a USB cable to your PC or Tablet – then measure.
With the addition of Ocean Professional, the Cobia Flex R/F truly becomes an indispensable X-ray QA tool. Perform your QA work without any worries – sensitivity, kV ranges, or waveform types. It is automatic!

Dose probe for use with Piranha, Cobia Flex or Cobia Sense. Intended for low dose rate measurements such as input dose rate to image intensifiers.
Light probe for use with Piranha, Cobia Flex, or Cobia Sense. Intended for brightness measurements (luminance) on monitors and film viewing boxes as well as measurements of ambient light (illuminance) in the viewing room.
T20 is a solid-state probe dedicated for measurements on Rad/Fluoro systems when it is crucial that the probe itself does not have any effect on the system output or disturb the X-ray beam.
CT Dose Profile probe for use with Piranha, Cobia Flex, or Cobia Sense (with PC com). The CT Dose Profiler is used for the evaluation of CT and CBCT systems. The probe fits into standard phantoms used for CTDI measurements.
The RTI CT Ion Chamber 10 cm is a rugged, cylindrical pencil-shaped ionization chamber for CTDI measurements. It is intended for measuring and monitoring the exposure output level of CT scanners in a phantom or free-in-air. CT dose index, CTDI, can be measured in accordance with IEC 61223-2-6.

RTI LoniMover™ gives you a new level of precision and allows you to perform most accurate measurements according to valid standards and methods, using CT ion chambers or CT Dose Profiler when running axial scans or when there is no patient table. The LoniMover™ helps the CT Dose Profiler to slide through X-ray fields of any width at a constant speed.
For X-ray focal spot measurements, to assure that the X-ray tube focal spot size is within acceptable limits. The Slit Camera can be rotated 90 degrees in the Slit Camera holder.
The Visi-X is optimized for light field/x-ray field alignment measurements.Simply darken the X-ray room and place your Visi-X under the X-ray tube. Adjust the light field and make your exposure. The radiation field will immediately be visualized by the glow of the special phosphor compound.It can also be used for checking the centering of the bucky tray.
